Battery with electrically insulating container

Abstract

The battery includes an electrode assembly in an interior of an electrically insulating container. The electrode assembly includes one or more first electrodes alternated with one or more second electrodes. The container is positioned in an interior of an electrically conducting battery case. The container being is constructed such that the battery case is not in electrical communication with the one or more first electrodes and the one or more second electrodes, and such that an electrolyte positioned in an interior of the container does not contact the battery case.

1 . A battery, comprising:
 an electrode assembly in an interior of an electrically insulating container, the electrode assembly including one or more first electrodes alternated with one or more second electrodes; and   the container being positioned in an interior of an electrically conducting battery case, the container being constructed such that the battery case is not in electrical communication with the one or more first electrodes and the one or more second electrodes, and such that an electrolyte positioned in an interior of the container does not contact the battery case.   
     
     
         2 . The battery of  claim 1 , wherein the electrolyte is not located outside of the container. 
     
     
         3 . The battery of  claim 1 , wherein the container includes a sealing member and a housing arranged such that the sealing member seals an opening in the housing. 
     
     
         4 . The battery of  claim 3 , wherein the housing surrounds the electrode assembly. 
     
     
         5 . The battery of  claim 3 , wherein the housing and the sealing member are constructed of the same material. 
     
     
         6 . The battery of  claim 3 , wherein the housing contacts the battery case. 
     
     
         7 . The battery of  claim 6 , wherein the electrode assembly contacts the housing. 
     
     
         8 . The battery of  claim 3 , wherein the cover member is sealed to the housing. 
     
     
         9 . The battery of  claim 3 , wherein the battery case includes a cover member in electrical communication with a case and the sealing member is immobilized on a cover member. 
     
     
         10 . The battery of  claim 9 , wherein the sealing member and the housing are each a thermoplastic. 
     
     
         11 . The battery of  claim 1 , wherein a first terminal that is accessible from an exterior of the battery case is in electrical communication with the one or more first electrodes and a second terminal that is accessible from an exterior of the battery case is in electrical communication with the one or more second electrodes. 
     
     
         12 . The battery of  claim 11 , wherein the first terminal is in electrical communication with a first electrical conductor that extends through the container and the second terminal is in electrical communication with a first electrical conductor that extends through the container. 
     
     
         13 . A method of fabricating a battery, comprising:
 fabricating an electrically insulating container that includes an electrode assembly in an interior of the container, the electrode assembly including one or more first electrodes alternated with one or more second electrodes; and   fabricating an electrically conducting battery case that includes the container in an interior of the battery case without the one or more first electrodes and the one or more second electrodes being in electrical communication with the battery case.   
     
     
         14 . The method of  claim 13 , wherein the battery case surrounds the electrode assembly. 
     
     
         15 . The method of  claim 13 , further comprising:
 positioning an electrolyte in an interior of the container without the electrolyte contacting the battery case after fabricating the battery case.   
     
     
         16 . The method of  claim 15 , wherein the electrolyte is not positioned outside of the container after fabricating the battery case. 
     
     
         17 . The method of  claim 13 , wherein fabricating the battery case includes attaching a cover member to a case. 
     
     
         18 . The method of  claim 17 , wherein the case surrounds the electrode assembly before the cover is attached to the case. 
     
     
         19 . The method of  claim 13 , wherein the container includes a sealing member and a housing arranged such that the sealing member seals an opening in the housing. 
     
     
         20 . The method of  claim 19 , wherein the housing surrounds the electrode assembly.
